Haha I've done that so many times. Just the other day I was talking to a coworker on the phone and before he hung up he said "ok, love you.. bye". As soon as hung up I started laughing and thought to myself did he really just say that? Not even 10 seconds went by and he called right back apologizing and said it's just a habit saying that at the end of a conversation from talking to his wife. I just laughed and said, "what, you don't love me any more?" LOL
